P.S. "" (Quotation mark) using for characters input, can’t be omitted.
Some WIFI SSID has special symbol which SM-120 keyboard do not support. And if you don’t use ACSII method to
input in scale, you may modify the AMS file and send back to scale.
C. Send back modified AMS file
Same produce and change ‘get’ command to ‘put’ (file should be store in same folder as received)
binary commend is very important here and can’t be omitted
D. Load AMS file on scale side
Under Z mode, use RZ+1457 (only effect after received AMS file)
